Fnb

My account was placed on hold on the 9th of December when I called the bank on the 10th was told my account was reported as ***** how I don't know someone put money into my account I told them I can replace that person money but their told me it needs to be investigated up until today their haven't called me back I have been going to the bank calling the ***** line their keep on putting me on hold for 30 minutes which is too much for me was given the person who is investigating the case number when I call it doesn't exist so if the bank can not help me what should I do I really need to use my account FNB is just disappointing very poor service...
